To implement data validation for the 'Score' column, I would select the entire column (or the range of cells where scores will be entered). Then, I would navigate to the 'Data' tab and select 'Data Validation'.

In the Data Validation dialog box:

• Allow: I would select 'List'.
• Source: I would enter the range of valid scores, e.g., 0-100. Alternatively, I could create a separate list of valid scores in another range and specify that range as the source.
• Error Alert: I would select 'Stop' to prevent invalid entries. I would then enter a custom error message, such as "Please enter a score between 0 and 100."
• Input Message: I would also consider adding an input message, such as "Enter a score between 0 and 100.", to guide the user.

This will ensure that users can only enter valid numerical scores within the specified range.
